Device for changing the roller guide segments of continuous casting plants

The invention relates to a device for changing the roller guide segments of continuous casting plants and represents a further development that described in the German patent specification 1.2j39.44O Invention.

According to the main patent, a device for removing and installing the individual segments forming the strand guide consists of one In addition to the strand guide, trolleys run in rails with support surfaces for the strand guide segments. The rails of the car run in an arc along the strand guide, with the center of curvature of the running rails coincides with the center of curvature of the strand guide. This device is a short-term Change of unusable leadership segments is possible without having to the continuous caster has to be converted.

The aim of the additional invention is a changing device for the guide segments several juxtaposed casting arteries. According to the invention this is achieved in that a car to change the Guide segments of these casting strands is provided, which can be transferred to the pairs of rails assigned to these casting strands. To this In this way, only one carriage is required to change the guide segments of all casting strands.

In the case of a change carriage on which deflection rollers are mounted, over which a cable pull provided as a drive is guided, can the pulleys can be releasably attached to the carriage.

According to a further feature of the invention, the Ural castors are mounted on an axis guided in the rails, the Car is provided with hook-like projections for receiving the axle.

This connection between the cable pull and the car is made by simple Placing the car with the crane on the rails closed, the hooks of the car gripping the axis c τ · pulleys. A cumbersome handling of the schwertη ropes is not here necessary.

An exemplary embodiment of the invention is shown in the drawing. £ 3 show:

Fig. 1 is a side view of a change carriage with a suspended Pulley axle

FIG. 2 shows the plan of FIG. 1

A carriage 8 for changing Stran ^ Uhrungssegraenten 4 is with his Running wheels 23 guided in rails 7, welohe next to the The strand guide run in an arc. To accommodate the guide segments 4 is the carriage 8 with lower support surfaces 11 and side Support surfaces 10 provided.

To pull the segments 4 onto the carriage 8 is between the support surfaces 11, a pull rod 24 is guided on rollers 25 and connected to an actuating cylinder 26 arranged below. on the tie rod is a head 27 for coupling to the respective segment arranged displaceably. A pawl 28 mounted in the head and under spring pressure latches in sequence when the segment is pushed open in recesses of the pull rod 24, so that the stroke of the actuating cylinder 26 is limited to the distance between the recesses can be.

The drive of the carriage 8 is carried out by ropes 14, which reduce the required tensile force is guided over pulleys 1j3 are. The pulleys 1j3 are mounted on an axle 29, whose The ends extend into the area of the running rails 7. At the Car 8 two hooks 30 are arranged, which the axis 29 in the operating position capture. At the lower end of the rails 7 are

intended to limit the travel range stops 3I, which 8 rear lugs 32 are assigned to the carriage

The upper web of the U-rails 7 is in the area of the stops 31 has been removed so that the carriage 8 is lifted by a crane at this point and running rails assigned to another strand guide can be discontinued. These parts are not shown in the drawing.

When the carriage 8 is lifted off, the connection between the hooks 30 and the axle 29, which remains with the deflection rollers 13 on the rails J , is released of the carriage 8 are detected, whereby the connection between the drive and carriage is established in a simple manner, without the cables H having to be lifted off the pulleys 13 and put back on again.
